DCRP has posted a review on the Epson PhotoPC 3000Z. Here is a snippet:
The 1.8" LCD display is very good: easy to read and smooth. It´s easy to smudge with both your nose and your fingers, though. Epson uses "software buttons" instead of fixed buttons, which means that those buttons around the LCD change depending on the situation. A menu on/off button (equivalent to the Display button on most cameras) turns off any info that is over the image on the LCD.Read more
They´re a little hard to see in the top right, but the zoom controls are well placed for easy thumb access. The optical zoom is responsive and smooth.
